I've recently implemented Facebook Login button and a Facebook "Like" button using XFBML. You can see the site on http://colnect.com
Everything works well with FireFox, Chrome, Opera & Safari.
However, IE doesn't show neither "login" or "like" buttons and no error message is available as well.
Any ideas?
Seems I'll be the kind of person to answer himself hoping it'll help someone.
For Internet Explorer to recognize Facebook you should add
xmlns:fb="http://www.facebook.com/2008/fbml" to your html tag, for me it's
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml" xml:lang="en"> The second problem I had was that IE doesn't support Array.indexOf() so here's the way around it:
if(!Array.indexOf){ Array.prototype.indexOf = function(obj){ for(var i=0; i<this.length; i++){ if(this[i]==obj){ return i; } } return -1; } } Hope it helps.
I solved my issue with this code. Rest of the solution didn't work for my case.
<script> window.fbAsyncInit = function() { FB.init({ appId : '330984983742', status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true // parse XFBML }); }; (function() { var e = document.createElement('script'); e.src = document.location.protocol + '//connect.facebook.net/<?php echo ($_SESSION["lang"]=="es")?"es_ES":"en_US"; ?>/all.js'; e.async = true; document.getElementById('fb-root').appendChild(e); FB.XFBML.parse('fb-stuff'); }()); </script> I hope it will help someone else.
For me what did that trick consistently was adding class='fb-like' to the <fb:like> tag.
For me, I needed a channel file as described in the FB Javascript SDK. I posted a response to a similar issue - perhaps it helps in your case too:
